Tire tread



FIG. 1 is a perspective view of a tire tread showing our new design, it being understood that the tread pattern repeats circumferentially throughout the outer circumference and shoulder of the tire, the opposite side perspective being identical thereto;

FIG. 2 is a front elevation view thereof;

FIG. 3 is a side elevation view of the right side thereof, the left side elevation being identical thereto; and,

FIG. 4 is an enlarged fragmentary view of the tire tread, better illustrating the claim boundary.

In the drawings, the broken line disclosure of the tire sidewall depicts environmental structure and forms no part of the claimed design. The dash-dot-dot-dash lines, as seen in FIG. 4, represent the boundary of the claimed design and the unclaimed tread grooves. 

CLAIM The ornamental design for a tire tread, as shown and described.
